SARS-CoV-2 S1 (RBD) Lambda C.37 (Peru), GFP/His-Tag citations Grey lines correspond to aRecombinant protein of the receptor binding domain (RBD), Mutant (L452Q F490S) of SARS CoV 2 (COVID 2019) Spike S1 from Wuhan pneumonia virus with C terminal His GFP Tag. The mutations L452Q F490S are characteristic for the SARS CoV 2 virus variant C. 37 emerged in South America (Peru) in late 2020. C. 37 is classified as Variant of Interest (VOI) and also known as Lambda variant. The mutations are affecting the receptor binding domain (RBD) of the
